Cong You Bing — Chinese Scallion Pancakes
China's savoury, flaky street snack: an unleavened dough rolled with oil and a blizzard of scallions, then coiled, flattened and pan-fried until shatteringly crisp and golden outside with chewy, layered, oniony insides. The trick to those famous flaky layers is the roll-coil-and-flatten technique that laminates oil through the dough. Cong you bing is quick, cheap and deeply moreish — torn into wedges and dipped in a soy-vinegar sauce, hot from the pan.
Make a soft dough with flour and hot water (a partly hot-water dough keeps it tender), knead briefly and rest it. Roll a piece out thin, brush with oil (or an oil-flour roux for extra flakiness), sprinkle with salt and lots of chopped scallions, then roll it up into a rope, coil the rope into a spiral, and flatten the spiral into a round — this laminates the oil and scallions into layers. Pan-fry in a little oil over medium heat, covered briefly then uncovered, until deep golden and crisp on both sides. Cut into wedges and serve with a soy-vinegar dip.
- The roll-into-a-rope, coil, and flatten technique is what creates the signature flaky layers.
- Use a soft dough (some hot water makes it tender) and rest it so it rolls thin without springing back.
- Pan-fry in a little oil over steady medium heat for crisp outsides and chewy, layered insides.

المكونات
Dough
- 250 g plain (all-purpose) flour
- 150 ml water (part boiling, part room temp)
- Pinch salt
Filling & frying
- 1 large bunch scallions, finely chopped
- Oil (and optionally a little oil-flour paste), for brushing
- Salt; oil for pan-frying
Dipping sauce
- 3 tbsp soy sauce; 1 tbsp black vinegar
- Chilli oil; a little sugar; sesame seeds
الطريقة
- خطوة01
Mix the flour with the water (stir in the boiling part first, then the room-temp water) and a pinch of salt, and knead briefly into a soft, smooth dough. Cover and rest at least 30 minutes so it relaxes and rolls easily.
- خطوة02
Divide the dough. Roll a piece out as thin as you can into a rectangle. Brush all over with oil (or an oil-flour paste for extra flakiness), sprinkle with salt and a generous layer of chopped scallions.
- خطوة03
Roll the dough up tightly from one long edge into a rope. Then coil the rope into a flat spiral (like a snail) and tuck the end under. Gently flatten and roll the spiral out into a round pancake — this creates the flaky layers.
- خطوة04
Heat a little oil in a pan over medium. Fry the pancake until deep golden and crisp on the bottom, then flip (cover for a minute to cook through, then uncover) and crisp the other side, 3–4 minutes a side.
- خطوة05
Mix the dipping sauce ingredients. Cut the hot pancake into wedges and serve immediately with the soy-vinegar dip.
Make ahead
Shape the pancakes ahead and freeze them raw (stacked with parchment) — then pan-fry straight from frozen whenever you want one, no thawing needed. The dough can also be made ahead and rested in the fridge. This make-and-freeze approach is how many people keep cong you bing on hand for a fast snack.
Storage
Best hot and crisp from the pan. Cooked pancakes keep a day and re-crisp well in a dry or lightly oiled pan (not the microwave, which softens them). Uncooked shaped pancakes freeze excellently — freeze flat with parchment between, then pan-fry from frozen, which is a great way to have them on demand.
Variations
Extra flaky
Brush with an oil-and-flour paste (you bing su) instead of plain oil before rolling for even more distinct layers.
Pancake rolls (cong you bing juan)
Wrap a cooked pancake around egg, sauce and vegetables for a popular Taiwanese street wrap.
With sesame
Press sesame seeds onto the outside before frying for extra crunch and nuttiness.

الأسئلة الشائعة
How do I get scallion pancakes flaky?
The key is lamination: roll the dough thin, brush it with oil (or an oil-flour paste), add the scallions, then roll it into a rope, coil the rope into a spiral, and flatten it back out. This folds many thin, oil-separated layers into the pancake, which puff apart and crisp as they fry. Skipping the roll-and-coil step gives a flat, bready pancake instead of a flaky one.
Why use hot water in the dough?
Using some boiling water (a partly hot-water dough) partially cooks the flour's gluten, making the dough softer, more pliable and more tender — easier to roll thin and giving a less chewy, more delicate result. A mix of boiling and room-temperature water balances tenderness with enough structure to hold the layers. All-cold-water dough works but is chewier and harder to roll.
Are scallion pancakes the same as Western pancakes?
No — despite the name, cong you bing are savoury, unleavened flatbreads, not fluffy sweet breakfast pancakes. They're made from a simple flour-and-water dough (no egg, milk, leavening or sugar), laminated with oil and scallions and pan-fried until crisp and flaky. Think more 'flaky flatbread' than 'pancake'. They're naturally vegan.
Can I freeze scallion pancakes?
Yes, and it's the best way to keep them. Shape the raw pancakes, stack them with parchment paper between, and freeze. Then pan-fry them straight from frozen (no thawing) over medium heat until crisp and cooked through. This gives you fresh, hot, flaky pancakes on demand and is how they're often sold frozen in Asian markets.
What dipping sauce goes with them?
A simple soy-and-black-vinegar dip is classic — soy sauce, Chinese black (Chinkiang) vinegar, often with a little chilli oil, sugar and sesame seeds or chopped scallion. The tangy, savoury sauce cuts the richness of the fried pancake. They're also good plain, or, in the Taiwanese style, wrapped around egg and sauce as a heartier snack.
